Not sure what would be considered a "credible source" but I would just use common sense.
There are only three ways a businessperson can react to a tax increase, they can decrease their profits, decrease wages, and/or increase prices. Any combination of these three things hurts consumers, wage-earners, and other businesspeople. The latter two are rather obvious so people tend to think that decreasing a businessperson's profits is the ideal situation but allow me to explain why this is also bad for average folks.
If a businessperson decreases his profits that means he/she either has less to invest into future production and/or less to spend on personal consumption. In the first case this hurts the wage earner and the consumer because it means he/she will earn less and/or pay more than would otherwise have been the case because investments would have tended to increase productivity, it also hurts the businesspeople who would have produced the factors of production that would have been invested in and of course the wage-earners who work for them. In the second case that the business person cuts back on consumption also hurts other businesspeople who would have produced those consumable goods that would have been demanded had the government not taxed more, this also hurts wage-earners who work for them as well.
Of course this model does not account for the possibility of benefits deriving whatever the government spends the money on, so the bottom line the philosophical question comes down to "Who do you think will spend the money more wisely you or the government?". I tend to think that a large bureaucracy with little to no accountability would tend to squander the money while individuals would be much more likely to exercise thrift and get more bang for their buck so to speak, of course that is just my opinion I don't have any credible sources to back that up other than my own critical thinking skills. The fact that much of what the government does with ridiculous regulations, wars, and whatnought actually hurts the economy further tends to reinforce my opinion.
Ultimately I think a good question for people is, If you think the government will spend your money more wisely than you why not give all your money to the government?", they will probably say but I need that money for rent, food, other bills and whatnought and you can cite that as proof that the government would not spend the money as wisely as they would. For if the government was spending the money as wisely as they would surely they would have provided for their rent, food, and other necessities? The truth is everyone knows giving money to the government is a bad investment that is why no one wants to do it because the expected value in return is far less than whatever you pay in, so instead of giving all their money to the government most people tend to spend it themselves on necessities, luxuries, investments etc. which they apparently consider better a deal.
